Abstract
BACKGROUND Pancreatic fistula (PF) is one of the most serious postoperative complications of gastrectomy. Misidentification of the boundary between the pancreas and the dissected fat is a primary concern. In this study, we focused on differences in the appearance of the pancreas and the dissected fat in actual surgical images and statistically analyzed the relationship between the pancreas and the dissected fat. METHODS We analyzed data from 109 gastric cancer patients who underwent curative gastrectomy between November 2018 and March 2023. Intraoperative images were taken from videos of lymph node dissections of Nos.6 and 8a regions, and the mean gray value of the areas was measured using ImageJ software for analysis. The visceral fat area (VFA) was evaluated by preoperative axial CT at the umbilical level using Ziostation software. RESULTS A significant correlation was observed between the fat/pancreas gray value ratio in the No.8a lymph node region and the drain/serum amylase ratio (P < 0.001). The fat/pancreas gray value ratio in the No.6 lymph node region correlated with VFA (P < 0.001). The VFA and drain/serum amylase ratio were significantly higher in the group with intra-abdominal complications (P = 0.004). CONCLUSIONS We revealed significant relationships between the fat/pancreas gray value ratio with drain/serum amylase and VFA. Detecting differences in gray values between the pancreas and the dissected fat may lead to a decrease in the drain/serum amylase ratio and PF.

Short-term outcomes of laparoscopic and robotic distal gastrectomy for gastric cancer: Real-world evidence from a large-scale inpatient database in Japan. J Surg Oncol 2024; 129:922-929.

Abstract
BACKGROUND AND OBJECTIVES Robotic distal gastrectomy (RDG) has been widely performed throughout Japan since it became insured in 2018. This study aimed to evaluate the short-term outcomes of RDG and laparoscopic distal gastrectomy (LDG) for gastric cancer using real-world data. METHODS A total of 4161 patients who underwent LDG (n = 3173) or RDG (n = 988) for gastric cancer between April 2018 and October 2022 were identified through the Japanese Diagnosis Procedure Combination Database, which covers 42 national university hospitals. The primary outcome was postoperative in-hospital mortality rate. The secondary outcomes were postoperative complication rates, time to diet resumption, and postoperative length of stay (LOS). RESULTS In-hospital mortality and postoperative complication rates in the RDG group were comparable with those in the LDG group (0.1% vs. 0.0%, p = 1.000, and 8.7% vs. 8.2%, p = 0.693, respectively). RDG was associated with a longer duration of anesthesia (325 vs. 262 min, p < 0.001), similar time to diet resumption (3 vs. 3 days, p < 0.001), and shorter postoperative LOS (10 vs. 11 days, p < 0.001) compared with LDG. CONCLUSIONS RDG was performed safely and provided shorter postoperative LOS, since it became covered by insurance in Japan.

Pancreatic thickness as a predictor of postoperative pancreatic fistula after laparoscopic or robotic gastrectomy. Surg Endosc 2023:10.1007/s00464-023-10021-0. [PMID: 36997651 DOI: 10.1007/s00464-023-10021-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 03/12/2023] [Indexed: 04/01/2023]
Abstract
BACKGROUND Despite technical advances in minimally invasive gastrectomy for gastric cancer, an increased incidence of postoperative pancreatic fistula (POPF) has been reported. POPF can cause infectious and bleeding complications, which could lead to surgery-related death; therefore, reduction of the post-gastrectomy POPF risk is crucial. This study aimed to investigate the importance of pancreatic anatomy as a predictor of POPF in patients undergoing laparoscopic or robotic gastrectomy. METHODS Data were collected from 331 consecutive patients who underwent laparoscopic or robotic gastrectomy for gastric cancer. The thickness of the pancreas anterior to the most ventral level of the splenic artery (TPS) was measured. The correlation between TPS and POPF incidence was investigated using univariate and multivariate analyses. RESULTS The cutoff value of TPS was 11.8 mm, which predicted a high drain amylase concentration on postoperative day 1, and patients were categorized into thin (Tn group) and thick TPS groups (Tk group). There was no significant difference in the background characteristics between the two groups, except for sex (P = 0.009) and body mass index (P < 0.001). The incidences of POPF grade B or higher (2% vs. 16%, P < 0.001), all postoperative complications of grade II or higher (12% vs. 28%, P = 0.004), and postoperative intra-abdominal infections of grade II or higher (4% vs. 17%, P = 0.001) were significantly higher in the Tk group. Multivariable analysis identified that high TPS was the only independent risk factor for grade B or higher POPF and grade II or higher postoperative intra-abdominal infectious complications. CONCLUSIONS The TPS is a specific predictive factor for POPF and postoperative intra-abdominal infectious complications in patients undergoing laparoscopic or robotic gastrectomy. Careful pancreatic manipulation during suprapancreatic lymphadenectomy is necessary for patients with increased TPS (> 11.8 mm) to avoid postoperative complications.
